Tips for Sexing and Breeding Leopard Geckos


Whitney has raised and bred different species of geckos, snakes, lizards, tortoises, and other exotics since 2003.

Breeding leopard geckos is relatively easy once you have the male and female geckos. If you decide to breed them, do not house the male and female together; this can cause stress on the female. Letting the male and female mate all the time can cause health concerns with the female, so do not let them mate unless you have the full intent of incubating the eggs. Otherwise, it just causes unnecessary stress on the female.

Just remember that even though it may be easy, breeding leopard geckos is NOT for everyone and not everyone should try it. It can get expensive, and it's not as easy to sell the babies as you may think. You can and will more than likely quickly become overrun with hatchlings. If you do not have proper experience with leopard geckos (i.e. you've only had yours for a few months), then it's suggested that you WAIT to have more experience before breeding.

Sexing Leopard Geckos

Once you've decided to breed your leopard geckos, you must make sure that you have a male and a female, otherwise you will not any babies. Plus, accidentally putting two males together in hopes of breeding them will only cause injury and possible death, so first you must make sure that you have one male and at least one female. It is hard to determine the gender of leopard geckos until they are about six months old, so when checking a baby gecko for its gender, a male may resemble a female.

How to tell a male from a female:

If you know at what temperature the gecko was incubated, it will give you a good idea as to what the gender is, but either way you should check the vent (base of the tail where it meets the body). Both genders will have a 'V' of femoral pores at the vent, but in females the femoral pores will appear much fainter than in males. Males also have two hemipenal bulges at the base of the tail, below the vent.

You must be certain of the gender of you gecko before you put two geckos together, so remember that the size of the head or the length of the gecko cannot determine the sex because there are always exceptions to the rules.

Appropriate Breeding Age

Leopard geckos should be fully grown before you think about breeding; make sure that they are at least one year old. If a female is too young, complications may arise, and the overall lifespan of the gecko can be shortened. The age is not the sole determining factor of breeding requirements. The female should also be in good condition, not underweight or unhealthy. She should be no less than 50 grams because she will actually lose weight while being gravid, as the egg production takes calcium from her bones and body.

Mating and Egg Laying

Usually, you will not see the mating process, but you will begin to notice bite marks on the female. The male will grab a hold of the female around her neck, but it is not uncommon to see marks on her body or tail. If you begin to notice sores or bullying, you need to remove the male. Usually, you will only need to keep the male with the female for a few days to a week.

As the eggs develop within the female, you will begin to notice the female gaining weight. The skin will begin to stretch, and the eggs will become visible in her abdomen. Occasionally, the first clutch will only consist of one egg, but usually, they come in pairs. The female will lay her eggs about every four to six weeks. First time breeders will typically have fewer eggs the first year, but you will find that leopard geckos can lay up to 10 eggs a season.

What a gravid (pregnant) gecko will need:

Have a laying box, or humid hide, where the female can lay her eggs. Fill the laying box with about one to two inches of damp vermiculite or perlite, found at garden stores. The laying box allows you some time before the eggs dehydrate, but sometimes the female will not lay the eggs within the laying box, so you must remove them immediately, or else they will dehydrate.

Typically, if the female doesn't lay the eggs within the laybox, they are not going to be fertile, but if you do catch them in time, you should try to incubate them anyway, as that is not always the case.

Incubating Leopard Gecko Eggs

You will need an incubator to ensure that the eggs stay at a constant temperature. Temperature fluctuations during incubation can cause deformities, if not potentially kill the embryo.

Types of Incubators

Homeade:

  • You can use old styrofoam coolers with heat tape attached to a thermostat.
  • An aquarium with an under water heater set to a particular temperature. Have the eggs in a tupperware of some sort, partially sitting in the water.

Commercial:

  • 1602-N Hovabator (Do not use a Hovabator with a turbo fan or with an automatic egg turner. The thermal fan will dry out the eggs even if you have optimum humidity in the deli cups.)
  • Nature's Spirit

Temperatures: The sex of leopard geckos is determined by the temperature of the incubator. Usually, if the egg is incubated for at 90º F, it will be a male, or if it is incubated at 80º F, it will be a female. If the eggs are incubated at 85º F, the chances your chances are 50/50 for either a male or a female, but you then run the chance of having "hot females" or "cold males," where they will not breed and are usually more aggressive.

Humidity: You should keep a cup or two of water within the incubator if you are using a bought incubator. This will raise the humidity levels. You can also pour water in the bottom of some bought incubators to accomplish the same thing.

Incubation Medium: When in the incubator the egg needs to be in some sort of container with a moistened bedding. Vermiculite and perlite work great. Hatch-rite is a new incubation medium that has great results as well; with Hatch-rite, you do not need to add water. Super Hatch is another good option that is now available.

Egg right before hatching

Hatching Leopard Geckos

The eggs will incubate for about 40–60 days. The higher the temperature, the faster the embryo will develop, and in turn the sooner it will hatch. About a week before the baby hatches, the egg will swell, becoming noticeably larger. A few hours before the baby hatches, you will notice deformation of the egg. Baby geckos have a hatching tooth that allows it to break out of the egg, but they soon loose the tooth after its purpose is served.

During the hatching process, the baby will take breaks, retreating back inside the egg, so if you are watching the baby hatch, do not worry. The overall process is fairly quick. The yolk sac will still be attached to the baby, so it is a good idea to leave the baby in its container for a little while so that the yolk sac can be rubbed off.

Caring for Leopard Gecko Hatchlings

Housing

Leopard gecko hatchlings must be housed with geckos of their size. If they are placed with larger geckos, they may be bullied and become stressed. This is the only time that you can house males together, but as they age, you will have to separate them. Just remember to house the geckos with others similar to them in size, reducing any problems that may occur.

Reptile carpet and paper towels are both great when housing young leopard geckos. Remember to place a small bowl of water in with the hatchlings. Make sure that it is not filled too deep to prevent the baby from falling into the water bowl. Overall, the hatchlings should be given the same treatment as an adult, receiving the same heat and overall care as an adult.

Diet

Hatchling leopard geckos will not eat until their first shed, which is usually about three to five days after hatching. You should have small crickets or mealworms ready to provide the hatchlings. Remember to appropriately size the feeder insects to no more than than the width of the space between its eyes.

Handling

Handing the hatchlings should be as minimal as possible because to the baby, you are gigantic, and handling the babies will frighten them, possibly stressing them out. You should allow the hatchling time to grow a little. Wait about a month before handling the babies, and when you think the babies are ready to be handled, start slow, just as you would the adults.

Nethalia on June 04, 2020:

mine are living together and at the age of 2 she still hasn't had aney fertel eggs why is that???

Alex on February 20, 2014:

I bought my Leopard Geckos 2 yrs ago. They have just laid an Egg in their water bowl/ hiding space.

I Don't know how to take care of a Egg.

Read up on it.

About different climates for genders the water shouldn't be to wet or to dry perlite would be best but I have left it in their I just noticed the Egg today couldn't be more then 12 -24 hrs old.

Not the male or female look different.

Whitney (author) from Georgia on June 06, 2012:

Usually by 6 months or so.

karen on June 05, 2012:

I have 2 Juvenal Leo's they are young. How old do they have to be before you can tell if they are male or female?

Thanks

Nick4 on April 16, 2012:

Okay so I just put my female and male together, it's been about 2 days. When will I know she is pregnant. I'm just a teen and I really want some babies.

Jmo on April 01, 2012:

I wasn't planning on breeding but I guess it just kinda happened. My female laid 2 eggs the other day. I was told u can't change how they lay or the eggs can die is this true? Also should the eggs keep their shape or will they look dented way before they're ready to hatch?

Whitney (author) from Georgia on January 30, 2012:

it's not kissing. biting is normal. breeding can sometimes get aggressive

Johnnie on January 24, 2012:

i just recently bought a male to breed my 2 females when i read up and learn more on it. well, i got the male out 2nite and one of the females and had em on the couch sittin together just to see how they would act towards each other. at first he started licking her like he was kissing her.. (which i thought was cute lol). then he started biting her back! so i put him up. is that normal, or do u think maybe the ppl told me wrong and ive looked wrong and they are both males?

Whitney (author) from Georgia on January 13, 2012:

It is normal, but it's not healthy or good. Impaction can occur

Quinn on January 08, 2012:

Alright thanks you and I looked in the talk tonight and say the smaller one just licking the sand and eating it. Is that normal?

Whitney (author) from Georgia on January 08, 2012:

I would separate them. I'm not sure what you mean by impacted guts.

Quinn on January 02, 2012:

They always seem to get along though and there hasn't been any fighting. So do i have to remove them? And that pretty much means that the smaller one is has imapcted guts? What should i do about this

Whitney (author) from Georgia on January 01, 2012:

It looks like both are males, but the pictures are dark. I see bulges and femoral pores on both. The one with the slightly skinnier tail definitely has the 'V', and the one with the bigger tail definitely has bulges. I assume the one with the bigger tail is older.

quinn1010 on December 30, 2011:

The smaller mack snow is the "female" and the bigger one (that is orangish-yellow, with a bigger tail) is the "male"!!

quinn1010 on December 30, 2011:

Whitney (author) from Georgia on December 30, 2011:

You can upload the pictures to photobucket, and post a direct link here.

Quinn101 on December 28, 2011:

Is there anyway I could upload a picture of oach of them so you could sex them? Because now I am having my doubts if the one really is a female. The both have two bulges at the start of the tail and they also have pore lines. Could i email or upload them? If so, how do I? Thank you so much!

Whitney (author) from Georgia on December 27, 2011:

Quinn, Females can produce eggs without being introduced to a male. The eggs are going to be infertile. If the gecko is egg bound, you will need to see a vet for a shot of oxytocin.These eggs will be infertile. By introducing the male, she will possibly lay fertile eggs. If she does become gravid, be prepared for many eggs.

Stocky, separate the two. In some cases, the male will not eat,a s he's more interested in mating, but I would recommend separating them.

Stocky B on December 26, 2011:

Hi i have had my leopard gecko a year now and have recently got a female for him but he has seemed to have gone off his food. if i filled his meal worm dish he would eat every last one within a night but there is still the same amount in there is this normal once introducing a female?

Quinn on December 23, 2011:

Okay so I got a leopard gecko going on two years ago. I always thought that it was a male but then i started feeling a ball on each side of its stomach. I waited about 3 months and the realized that it might have impacted intestines. So i called that fish place that pet place and talked to someone in the reptile room. She said that the gecko is a girl and that it is pregnant. That was a shock. But i only had her and no female. so I don't understand how she produced aggs. She said that she might be "egg-bound" and could possibly die. She then told me how to make a place for her to lay the eggs but they would be infertile and to just throw them out. But she still didn't lay them and i got worried. So a couple days later I bought an adult male from a friend and put them in the tenk. They are fine and don't fight. Do you think that she will lay the eggs? and if she does do you think that they will be fertile? I really need to know soon. Please help!

Rich on December 12, 2011:

My gecko is pregnant! what do i need to buy to be successful as its my first time breeding?

Whitney (author) from Georgia on November 17, 2011:

It's a first generation Cremesicle, which is the direct offspring of a super hypo tangerine and a snow. These will vary greatly.

G on November 17, 2011:

What's an F1 creamsicle and how can i get one?

Whitney (author) from Georgia on September 30, 2011:

At four months old, both geckos are not nearly old enough. YOu do not want to breed yoru female until she is at least a year old and over 50 grams. You will want to keep the two geckos separated, as the male will become sexually active before the female should be bred.

RCC0123 on September 29, 2011:

One more question. I got two of the same leapard geckos in the same place at the same time and one has turned out to be twice the size of the other. What do you think on that.

RCC0123 on September 29, 2011:

I am new to all of this breeding stuff. Mine are about four months old. When should I expect to make or prepair an incubator for the babies?

Whitney (author) from Georgia on September 29, 2011:

It is possible that the female can become egg bound. It's not because of sticky eggs but because of calcium concerns. The male will stress out the female, and potentially bully her. THere will be biting associated, as well.

julien77 on September 26, 2011:

im thinking about breeding my leopard gecko's but i don't know if they will get injured in any way laying the egg i have heard from someone that the female may have trouble in laying the egg because the egg is sticky and will not come out and the female will get injured please answer :(

Whitney (author) from Georgia on September 23, 2011:

They do not eat until they have had their first shed.

NickiFierce920 on September 22, 2011:

Ok I put it in a tank. Should I feed my hatchling now? It hatched two days ago. I tried to feed it but it doesn't seem to be interested. Is my gecko hungry?

Whitney (author) from Georgia on September 21, 2011:

If the hatchlings have hatched, set them in their enclosure.

NickiFierce920 on September 20, 2011:

My Leopard gecko just hatched today..Im wondering when i should take it out of the incubator...Is it too soon to do so?

Whitney (author) from Georgia on September 02, 2011:

Yes, that is what I'm saying.

Pierce on September 02, 2011:

Hey there so Whitney, you're sayin that if I have a male and a female together they will mate no matter what?!

chris on August 17, 2011:

When bringing the two together to mate do i put the male in the females tank or bring the female to the males tank?

Michelle on July 19, 2011:

Hiya Whitney.

Would it be ok 2 hav 2 24"inch tanks for the male & female & when im ready to breed them, would it be ok to pop the male in with the female in her 24" inch tank or wud it be best to get her a bigger tank for mating?

Really love this website & find it very useful.

Kind regards

Michelle.

Whitney (author) from Georgia on April 08, 2011:

They are dehydrating if they are denting. They could be infertile.

Chris on April 06, 2011:

My female has laid eggs recently this is her first clutch and when she laid them they were stuck together a little bit at the end of the egg and they also have fell in what does that mean?

Morgan on March 09, 2011:

Hrm...I always wonder one thing: the people say they will keep all the hatchlings, do they realise they might need 16 tanks and heaters? That aside, I now know why they were so eager to give me a gecko...

To anyone buying a gecko: check the Recues first.

Whitney (author) from Georgia on February 27, 2011:

John, It may be dehydrating or infertile. Just depends.

Randolph, Just keep watch. If it's her first time, she may retain them and reabsorb them. She may become egg bound, or she may not be on schedule. They don't all lay at the exact same time or on a by the day exact calendar appointment.

randolph on February 26, 2011:

Hi there ive already asked a few questions about leopard geckos eggs. I have a leopard gecko, she id definitely gravid but she isn't laying... they lay 4 weeks after mating i believe and so she should have laid about the 2nd of feburary and now its the 26th. any ideas? thanks

jonnojohnb on February 25, 2011:

Hey there,

When a Geckos egg has a bump in it, does it necessarily mean that its infertile or just needs more humidity thankyou

Whitney (author) from Georgia on February 22, 2011:

Not really. Not under most captive bred circumstances.

nathan on February 21, 2011:

Is there any way to let the gecko mate and lay the eggs and hatch them on there own without human help and still have a healthy cluthch

Whitney (author) from Georgia on February 17, 2011:

The gray color more than likely meant that the gecko was going into shed. THey eat their shed, so you wouldn't really see it unless you caught the gecko in action or if some got left over.

They need to be kept separate, as you won't always see them breed,and trust me, they have.

They sleep all the time because they are nocturnal and are awake during the night.

Ashley on February 16, 2011:

I gotten a male and female from my teacher and they never shown the signs of breeding but they did like once during the spring but the female wasn't interested so the male stopped and then the ended up sleeping in the same area. All they do is sleep now. I don't even know the age. when i got them they were all gray but now the female is turing yellow and the male is slowly turning a yellowish color but still a little bit gray. So i don't know the age of them.

Whitney (author) from Georgia on February 09, 2011:

The tail wag has nothing to do with breeding.

You should not have them housed together because you haven't quarantined the new male for up to 60 days to ensure health.

ben on February 09, 2011:

hi i have got 6 leopard geckos i have 2 males and 4 females, my oldest gecko (gordon) is 17 and is as nearly as old as me hes a really good friend i have had him since i was a kid and i was hoping he will be breeding but then i found out hes to old but i have one female who is old enough all the rest are juvinales and i have bought a new male (sunny) he is 4 years old and bought him a few days ago this morning before i went out i had them toghther and he started wagging his tail but i fought im not ready at the moment but later or now i diecided im going to be breeding and he wont do the wiggley tail any more hes just not interested in her anymore should i be housing them toghther or does it not really matter ok guys thanks

Leopard geckos:

males:

gordon (17 years)

sunny (4 years)

females:

luna (1 years)

minty (1 year)

squirt (5 months)

lily (3 years)

thanks everyone

damensheppard on February 03, 2011:

im getting my lepord gecko on the 19th i cant wait

Whitney (author) from Georgia on January 17, 2011:

Nope. Male will breed with a female no matter what. Separate them. It will be better for both geckos.

Dawson on January 15, 2011:

Is there a way to prevent breeding? besides seperating my male and female. My female keeps laying eggs and I feel bad not taking care of the eggs but what I keep reading is it involves alot of work and is difficult.

Whitney (author) from Georgia on January 10, 2011:

If they've started laying even 1 or 2 eggs, then they are gravid and breeding.

If this is their first year breeding, the likelihood that the majority of the eggs will be infertile is going to be high. I've had first time breeders lay consistently infertile eggs the first full year of breeding.

No way to increase odds of fertile.

Separate the male once first eggs are laid. No reason to keep him in there. He won't be lonely by himself.

randolph on January 09, 2011:

i have currently 2 females and 1 male leopard gecko housed together... one of them has laid 4 eggs in about 2-3 weeks and the other one has laid 2 eggs.. do yout hink they are in season which means they will lay two egg every2-4 weeks? also the 6 eggs ive had all seem to be infertile... any idea how to increase my chances of making the eggs acctually fertile? and one last thing.. what shoudl id o to my geckos to make sure they arnt seriously hurt during breeding? thanks

Whitney (author) from Georgia on December 26, 2010:

For the most part, if there isn't a pink bulls eye, the eggs aren't fertile.

Geckos will generally lay infertile eggs in crazy places, like the water bowl.

Just make sure to provide a humide hide for fertile eggs.

randolph on December 24, 2010:

hi there, qucik question, my leopard gecko layed 2 eggs about 6-7 days ago, zhe layed both of them in water. luckily i managed to catch them within an hour fo them being layed. i put them into the incubator, unfortunately one fo them caved in and died but the other one looks in good condition. i was jsut wondering how long does it start for the egg to develop? its been a week and it looks completely yellow inside apart form 1 small pink vein near the top... any diea if it could eb fertile and how long itll be until i will know? thanks

Whitney (author) from Georgia on December 20, 2010:

The "puffs" behind the arms means nothing in regards to being gravid. That is normal. It's like fatty buildup

If you dont' know what you're doing, you don't need to breed or get another gecko. I suggest learning about what you have before getting more and before breeding.

Breeding risks the health of the gecko and if you don't know what you're doing, you can end up causing great damage.

Make sure to monitory temperature with a digital thermometer with a probe. DO NOT estimate.

Also, try not getting animals from pet stores. They are generally going to be sick and laden with parasites. Do not believe them when you see the sign that says all are checked by a vet. They are not, unless they already exhibited signs of illness.

Rania on December 19, 2010:

Sorry it's actually a puff on both sides and it's about a centimeter long ,behind her arms

rania on December 19, 2010:

hi,

i talked to you before about getting another gecko on one of your other hub page. I couldnt get the gecko cause he already sold it but i have a problem with my female leopard gecko. I will give you all the details i can because im really worried about her. She has been in with a male for about a week now and i went to petco to see if she was pregnant and someone said she was (i know petco isn't reliable so im not sure). but yesterday morning i saw that she shedded overnight. Later that same day in the afternoon i took her out and noticed right between her head and arms her skin was puffed up on both sides. I tried to research and didnt find anything. Its been like this for a day now and its not shed for sure. She and the male didnt fight because theres no bites or anything both are healthy. She ate 10 crickets the day before that. The temperature is at high 80s low 90s. She has a log on the cool side and one on the warm side. I moistened the humid hide before she shedded. She is about 5 years old and a mack snow i think. im not sure i want to take her to the vet because it can be very expensive and theres is no reptile vet in my area but if its urgent i will. And she is on paper towels and i change her light day and night and she also has a heat pad. Sorry there is so much information its just i dont know what caused it so im telling you everything. Do you know whats wrong with her?

Whitney (author) from Georgia on October 26, 2010:

You would need to upload the picture to photobuck or something like that and post the direct link.

Sean on October 26, 2010:

I'm on my blackberry and I have a picture of him on here. How do I post it?

Whitney (author) from Georgia on October 25, 2010:

Please post a picture, as if you truly have a 12" leopard gecko, it would be the rarest find. I do not believe it.

Sean on October 24, 2010:

I have a leopard gecko that's about 8 years old and he's about a foot long and I want to breed him because he's so large. I bought a female a few weeks ago and have it in a separate cage intill it gets big enough but the size differnce is so much I don't know if she would ever be big enough. The one time I put her in the same cage he looked like he was going to try and eat her (I do feed him pinky mice some time I don't know if he was confused). I just want to know what some people think.

Whitney (author) from Georgia on October 15, 2010:

Definitely remove the sand to prevent impaction again.

Be leery of continuing to breed this gecko as she's having such a hard time.

It is good she was able to get out the impaction and the eggs

They generally don't stick together, but just leave them as is, as you can tear the eggs easily.

DG on October 14, 2010:

Just an update.... she began to shed again, still hadn't eaten, so i took her to the vet. WE did some Xrays, found she was impacted from sand. Luckily, it could have been worse, as the blockage wasn't complete. After a week of warm baths 3 times a day along with Gatorade and a Lizard med (Lactolose) w/ no solid food, i awoke this morning to find she laid 2 BEAUTIFUL white eggs!!!! I put them in the incubator right away and set it @ 81......weird thing is the eggs are kinda stuck together.... i'm sure i could pry them away but i don't dare..... is this ok? are the eggs fine? ...Now that she's laid the eggs, my carrot tail seems much happier

Whitney (author) from Georgia on September 29, 2010:

Typically, they lay 2 once a month. I have had females lay two every two weeks, or one every few months. Give it some time.

They can lay many, but in some cases, the first year can be slow.

All females have the potential for up to 16 a year.

You're also at the end of the average breeding season, so keep that in mind.

DG on September 29, 2010:

Thanks for the response! Besides the one in her tummy, how many more should i expect? She hasn't laid since 9/12 so i'm a bit concerned.....is this big a gap between laying ok?

Whitney (author) from Georgia on September 29, 2010:

The egg is a dud. Just through it out. It's not going to hatch.

Not eating for just a little over a week isn't anything major right now, but sometimes there are some females who do not take well to breeding. I have had a few that will lose nearly all their weight, making them bad breeders.

The egg is brown, it's not fertile. Fertile eggs are white. She more than likely laid one because it was her first time breeding and her first clutch. Or she'll lay the other one within a week or so.

I've had one female start off her first year breeding laying one egg every other week or so.

DG on September 28, 2010:

My Carrot Tail laid an egg on 9/12...... she only laid one egg, it's 95% brown.... i've been incubating it @ 81 degrees consistently..... This egg is my gecko's 1st, laid it in a egg box w/ vermiculite .... she's not eating, not even wax worms, hasn't for about a week and a half.... mood seems ok though...just had 2 sheds within a 3 week period....i have confirmed she still has an egg in her........how can i tell the egg she just laid is not infertile? Why did she only lay one?

Whitney (author) from Georgia on September 23, 2010:

Mack snow is a dominant trait, and depending on what you breed the gecko to, you should get a mack. I've bred macks with shtctb's, for F1 creamsicles, and got a mix of tangs, creams, and snows. I've bred my mack with my tang enigma, and have gotten snows. Mack snow is a dominant trait.

Also, keep in mind many breeders offer mack snows at reptile shows and online, so there shouldn't be any reason why you wouldn't be able to find one. There are many, MANY breeders out there with TONS of leopard geckos available. Many breeders are near begging people to buy because there are so many geckos available and not that many people buying.

CorinPoore on September 22, 2010:

Im planning on buying a mack snow leopard gecko next week and i was wondering can you breed a mack snow with any other morph of leopard gecko and the offspring have a chance of being on or the other morph ? Only because im worried i may not be able to get hold of another mack snow?

Whitney (author) from Georgia on September 12, 2010:

No that is not correct. They are all temperature dependent.

abc123 on September 12, 2010:

I've heard that when you breed mack snows, they would have more males than females, even if they are incubated for female. Is that true?

Whitney (author) from Georgia on September 07, 2010:

Too high humidity.

There are many feed stores that sell hovabators. You can purchase one online and have it shipped to you, or you can make one using a styrofoam box, heat tape, and a good thermostat.

Thanks for the reply. I can't find an incubator near me to buy.. Why did your eggs mold in the incubator? I set one up (with no eggs), and so far the temp has been steady at 81F (even in the containers) - it hasn't fluctuated at all. I still have yet to get a digital hygrometer.

Thanks!

Whitney (author) from Georgia on September 05, 2010:

LeoGirl, I tried the aquarium method before, filling the tank half way of water and using an aquarium heater to stabilize the temperatures. I had trouble keeping the containers with the eggs from floating. I also had trouble keeping the water temperatures truly stable. I did not hatch anything via that method. All of the eggs molded. I would not recommend this method.

The method you describe won't work, as the dry perlite will dehydrate the eggs. Not sure why you wouldn't want to just purchase a real incubator.

Morgan, I would remove sand as a main substrate in the enclosure, as impaction is a huge concern. I would also create one enclosure for the female and another for the male, as they should not be housed together year-round. As for the eggs, they need to be removed immediately, as the sand will dehydrate them. They need to be placed in a moist substrate in an incubator that will provide stable temperatures that will not fluctuate.

morgan on September 05, 2010:

my female layed two eggs and barried them just alittle bit in the sand and its very warm cause of the heat pad and she lays on them would they be ok and when would be the best time to separate the parents from the eggs if shes laying on them

LeoGirl575 from Canada on September 05, 2010:

I have a question. I want to use the aquarium method - Put the eggs in a container, and the container in water that's heated. Will this work? Has it worked for you before?

And are you supposed to put a lid on the aquarium that you have the container of eggs in? Thanks!

See, this is what I was thinking:

I am going to get a small-ish plastic container, fill it partially with water, put and aquarium heater inside (heat to 80F), get another container that will fit inside the one with water, put perlite in there or something, not moisten it at ALL, put a lid on it and poke a couple holes, put the eggs inside, and put a lid on top of the bigger container, with no holes. Open it occasionally for air exchange. Will that work??

Whitney (author) from Georgia on August 24, 2010:

If they're dented you may want to make sure humidity is still good. Try putting a little layer of incubation medium over the eggs to help hydrate and plump them up. Leave them alone for now, and just hope they're ok. Try finding a place that's out of the way for your incubator for next time

randolph on August 24, 2010:

they had been incubating for about 2 weeks, my cleaner knocked the incubator and didnt tell me, so it was about 1 day before i noticed, couple of days later(today which is about 5 days after they had been knocked, both of the eggs have dents in them now, does that mean they wont hatch now? they eggs are pink inside still and i can see a few vains on them.. please let me know

Whitney (author) from Georgia on August 22, 2010:

What caused it to roll over? Depending on how long they've been incubating and depending on how long it was rolled over, it may or may not hatch. The fetus will generally drown if tilted.

randolph on August 21, 2010:

hi there, my loepard gecko laid two eggs about 2 weeks ago, i have had them in incubation, but i onyl noticed today, that oen of the eggs had been turned over... does that mean it wont hatch now?

Whitney (author) from Georgia on August 17, 2010:

Even by separating, you've already introduced your female to illness. Research is key and patience is a virtue.

Most breeders will introduce them at the end of the year or beginning of the next year.

Remember the market is saturated with people like you who think they can breed and get rid of easily. The market is full of geckos who need homes, and not enough people who want them.

K8 on August 16, 2010:

Ok, i just seperated them. Breeding season is in spring right? Should i put them together for a little bit then?

Whitney (author) from Georgia on August 16, 2010:

K8, I was just reminded of someone I had been helping with a gecko she thought was impacted with sand.. I guessed egg bound because she was also housed with a male and another female, I believe. She has spent nearly $300 (plus free xrays and treatment that was over $100) and the treatments still hasn't helped. Her female is getting worse and she can't afford further treatment. Are you prepared for this in case of?

Whitney (author) from Georgia on August 15, 2010:

Quarantine the male before putting him with the female to ensure that he doesn't have any illnesses. New reptiles should be quaranined at least 30-90 days before introducing to existing reptiles. By introducing them before quarantine, your current gecko may contract a parasite.

Signs of aggression may include biting,bullying, etc.

Again, I ask where will you house up to 16 hatchlings? How will you get rid of them?

What happens if your female gets overly stressed, ill, or egg bound caused by breeding problems? Will you be able to afford veterinary care?

K8 on August 15, 2010:

I finally got my mail and when i put him in with her today he began wagging his tail really fast. Then she got on top of him and they stayed like that for a while. Is fit any sign of aggression or what

Whitney (author) from Georgia on August 13, 2010:

It doesn't have anything to do with the tail, but the overall weight of the gecko. The female should be at least 55-60+ grams.

K8 on August 12, 2010:

thank you, i didnt know about that. Im just gonna try it and see how it goes. How fat should my geckos tail be?

Whitney (author) from Georgia on August 12, 2010:

Bred one time, one female may lay up to 16 eggs.

Not only is is super hard to sell, or give away for free, it's hard on the female's body. Some do not take to breeding well. I have one female that will become skin and bones during breeding season. I have bred her twice, and this is the last year I'm breeding her. I've known people who have had females become egg bound and need veterinary care. I've seen geckos nearly die from stress of breeding and laying eggs. Even geckos who start in great health, can have a lot of problems. That is something to keep in mind as well.

K8 on August 11, 2010:

Well im not a serious breeder i just recently decided to breed my 1 female gecko. She's my first and only one but i just want to get a male. im not gonna have a group or anything. i know im gonna have a hard time selling but i know a couple locals who may want them.

Whitney (author) from Georgia on August 11, 2010:

You can, but it's not ideal to keep the male with the female for too long, as it can cause undue stress. It's best to separate.

You're still considering breeding with average, mediocre geckos? You're going to have a super hard time selling.

K8 on August 11, 2010:

i have a normal female what do you think is best to breed with her. I have'nt yet gotten the male

K8 on August 11, 2010:

When your female is pregnant is it safe to keep the male with her? Also after the male mates with her and you keep him in the same cage when is the next time he'll probably mate with her again.

Whitney (author) from Georgia on August 11, 2010:

High yellow is just one step above a normal. You'd be lucky to find people who want them, much less who will pay any more than $10 or $15 for them. I sold normals with reduced mult-colored spots for $15 last year, and bell albinos for $20. That's all that I could get for them. People want high-end like various enigma morphs (but even many of these are selling for $50 now), super red tangerines, and a few others.

K8 on August 10, 2010:

What if you get unique ones like a high yellow, will you have a better chance of selling

Whitney (author) from Georgia on August 10, 2010:

I would not leave the eggs in with the female's heat pad, as the temperatures are not stable. You do not want more than a 2 degree fluctuation. I recommend buying or making an incubator.

I don't have any advice to convince people to buy. Without a reputation as a seller and reputable breeder, you won't be able to sell easily. I know people that have reputations of 5 years, and are still having trouble selling, myself included, and I've got a good customer base.

Keep in mind that right now just about everyone with a gecko tries to breed, which means the available supply is super high, and the demand is low. It's hard for anyone and nearly everyone to sell their geckos, even at dirt cheap prices.

K8 on August 10, 2010:

Also some people recommend to keep the eggs with the female in the cage over the heat pad in a homemade incubator. What do you recommend

K8 on August 10, 2010:

I want to breed my female gecko but do you know how to convince people to buy your geckos instead of some from petstores. Im afraid people might not by mine and I'll have to many mouths to feed.

Whitney (author) from Georgia on August 03, 2010:

It's best to have the surface temperature on the hot side of the tank to be right around 90F.

Angel on August 02, 2010:

I actually have a digital thermometer set up with the probe in the deli dish to try to moniter the temp. Doing my best to keep it in the 80's.


What is the ideal time of year to breed them?

You can attempt to artificially initiate breeding behaviors in your Leos if you have the time and are dedicated to it. However, you may increase your chances of a successful hatch—and reduce your efforts and intervention—if you follow their natural breeding timeline and habits.

Thankfully, leopard geckos have a lengthy breeding season, which gives you plenty of time and many chances to see babies.

In the northern hemisphere, adults are usually ready to breed starting around January and going through September. However, some females may begin ovulating much later.

Ovulation depends on many factors, but the time of year they hatched has a big impact. Early hatchers may ovulate sooner and later hatchers can ovulate later in the season.

The natural start of the leopard gecko breeding season is easy to spot. When it's time, you may notice some new behaviors and changes in eating habits. If your adult male gecko suddenly refuses to eat or exhibits other odd feeding habits, it's likely due to entering the breeding season.

Some even refuse to eat through the entire process, but this is completely normal. Females will often demand more food and seem ravenous at feeding times—this is also normal.


Tips for Sexing and Breeding Leopard Geckos - pets

Generally, breeding leopard geckos is easy once you have the male and female geckos. But you have to take note that if you do not have the full intent of incubating the eggs, do not house the male and the female together. The male gecko should only be placed in the female’s terrarium half an hour each day for three days. Letting them mate all the time can cause unnecessary stress and health concerns to the female.

Checking the gender of these geckos is relatively difficult until they are about six months old. So when checking a baby gecko for its gender, a male may look like a female. It goes without saying that the initial step in breeding process of geckos is to make sure that you have one male and one female gecko.

Leopard geckos should be at least one year old before you think about breeding make sure that they are fullygrown. If the female is too young, there will be complications, and the overall lifespan of the gecko may be shortened or disrupted.

However, the age is not the only thing that a breeder should consider. The female should also be in a good condition not underweight or unhealthy. The female gecko should be no less than 50 grams because the she will actually lose weight while being gravid, as the egg production will absorb calcium from her bones and body.

Unlike breeding dogs, breeding leopard geckos are much easier. But do not expect results immediately. After putting the male and female geckos in one terrarium, you will notice signs of aggression and biting. If the female is not in the mood for sex, she will strike back, usually by biting him as well.

All of these are parts of the mating process. If, after a few days they still have not mated, consider putting in another female gecko. Well, you know how males are!

Once they do mate, you’ll have one or two eggs in four weeks. Do not forget to provide a laying box for the female, which should be filled with one measure of water and one measure of sand. Add your water slowly. The box should have the right moisture because the eggs will grow moldy if the box is too wet. Transfer the laid eggs to a shoebox and incubate them at 85 degrees Fahrenheit. It is very important to note that the temperature of the incubator will determine the sex of the hatchlings.

Now you know everything there is to know in breeding leopard geckos. So, good luck and happy breeding!

So basically I have 2 Leos. One is Daisy who I think is female and Seymour is male. The old owners told me that they were female but I checked and I don’t think so. So I think Daisy is very big for a female and Seymour is small for a male. He has only grown a little Please help I am confused

look at the bottom near tail 2 humps male 0 female

Is there an age you have to stop breeding?
Like my gecko is 10 can she still start breeding?

As far as I am aware, leos can breed through their whole life.

Thanks for this instuctable. I am planning on breeding my leos once I get a male, so this is really helpful.

By the way, I'm not sure what morph they are, so if you know, could you tell me?

can you put a female into a Male tank?

as long as they don"t fight

I woke up this morning to find My gekos laid eggs and I was unprepared for it because I was told the there both male. She laid them in her water bowl. I carefully removed them and laid them in a cup with bamp moss. Is that ok until I can get vermiculite? Also I have no clue how long they had been under water and now they look like the are suck togather. Will they be ok?

Ya they will be fine. it’s okay for reptile geckos lay eggs and you shouldn’t of had them in the same cage if you where told they were both males bc if they where you put them in chance of fighting.

Yes but make sure the little ones don't eat the vermiculite

Boi just got two leopard geckos male and female I was told there nine months but they seem small for that age my female has not ate yet but the male has jumped right into eating he actauLly at 9 Pin head size crickets she didn't eat any should I try and separate her into anothe tank or container to eat or due you think it's just stress from new environment and give her a few days to get use to ? If I do give it a few days and she doesn't eat what should I do I also will be going to a reptile show this Saturday and was wondering can I have two females done male in the same enclosure I have a 30 gallon tank and plants breed when age appropriate thank you

If your gecko isn’t eating maybe she just doesn’t like the food. When I got t my first gecko speckles I gave her two crickets And she wasn’t eating so I went to meal worms and wax worms. Now that is all I feed my two geckos bc nether of them like crickets.


Secrets And Tips For Successful Leopard Gecko Breeders

The leopard geckos or the Eublepharus Macularius, do make intriguing and fascinating pets. Apart from their interesting appearance, these lizards are among the breeds that most lizard lovers prefers for the fact that they are easy to care for. Many of the first-time handlers have easily shifted to become expert leopard gecko breeders in no time.

But before we go any further, there are several things that potential gecko breeders must take into consideration: the sex of your leopard gecko and sexual maturity.

In determining the sex of your leopard gecko, the first thing that breeders need to know is when to try and figure that out. It is very tricky since male leopard geckos appear as females not until they have reached the right age. Right age would mean breeders will have to wait at least six months to accurately identify the lizard's sex. To do this, you must position your gecko upside down and holding it by the base of tail, male lizards tend to have a v-shaped pore formation and two pronounced bulges on both side of its tail while female lizards tend to lack both characteristics.

The breeds' sexual maturity is generally attained at eight months for males who usually weighs at least 45g while female geckos reach sexually maturity in a year for females and weighs at around 50g.

Breeding leopard geckos is as not as tricky as dog breeding where you need a shooter to get it done. Breeders' job is simple they have just to place the male and female lizards in one tank for a period of two days. One will notice the male gecko will begin to "pick-on" or engage with the female gecko. If the female chose to be unconcerned, she will tend to be aggressive and fight back. If after the two-day holding period, nothing transpires, take the pair and place them in different tanks and try again in a few days. If breeding is still unsuccessful, maybe you can introduce another female with the male gecko. In successful mating, you will tend to find two eggs in about four weeks. By that time, you should make sure that you already have a laying box. A small plastic container like a tub of margarine is ideal, place sand and water in the container with a ratio of 1:1.

You should laid eggs to a shoebox and incubate them. Make sure that you observe and monitor temperature as this would be the main determinant of the sex of your hatchlings. You have to incubate or keep them warm at around 80 degrees Fahrenheit if you wish to have female hatchlings, while 90 degrees will yield male hatchlings. But if you wish to have mixed genders, it is recommended to incubate your eggs at 85 degrees.

Breeding leopard geckos may be overwhelming at first, but it is really easily as it sounds. The best way to start is just to give it a go, who knows you might enjoy it.


1. Leopard Geckos are a long term commitment

All pets need lots of love, care, and attention from their humans. Reptiles may not be as demanding of attention as other pets, but they do need your constant love to remain happy. One of the largest lizards, Leopard Geckos are one of the easiest pets to keep and are usually termed as ‘beginner pets’. However, while keeping Leopard Geckos, you must remember that they are long term pets and need a constant commitment from their owner.

A female Leopard Gecko as a pet can easily live up to 10 years, whereas a male Gecko can live up to 20 years. If you take good care of your pet lizard, they can live more than a puppy. When you bring one home, make sure you know the age of your lizard. Most pet parents do not like to bring baby geckos home and prefer one which is at least 2 years old.
